I desparately need information on what to expect in terms of medical needs for the care for terminal liver cancer.

My mom was diagnosed with terminal metastatic liver cancer and was given 6 months at best. There is good possibility that it could be much shorter given that she was showing signs for liver failure. She lives in Canda and I live in US. Trying to figure out what the medical cost will be if we move her to US so she can spend her final months with her loved ones. Chances are she wont do any cancer treatment, just try to stay comfortable.

type of cancer related drugs? How frequent?
